This breaking news story will be continuously updated as more information becomes available.

10:36 p.m.: An unnamed civilian employee of the U.S. Army's Human Resources Command who was was shot during the shooting incident has been pronounced dead at Ireland Army Community Hospital, according to WDRB News.

"Special Agents from the U.S. Army Criminal Investigation Command are investigating a personal incident and not a random act of violence," Chris Grey, a spokesman for the Army's investigative agency told WDRB. Police are looking for a man described as 5'9" tall and African-American who may have been riding a black Yamaha motorcycle, WDRB reports.

8:52 p.m.: A military official with knowledge of the situation tells NBC News that a civilian was taken to a nearby hospital via helicopter.

8:47 p.m. Update: Officials at the Hardin County Sheriff's Office, the central Kentucky State Police post and the local Elizabethtown State Police post all declined to provide any information regarding the shooting. Calls and emails to the U.S. Army's Media Relations Division at the Pentagon in Washington, D.C., as well as to the Fort Knox Public Affairs Office went unanswered Wednesday evening.

The shooting reportedly took place at the U.S. Army's Fort Knox post in Kentucky at about 5 p.m. Wednesday.

There was very little available information about the incident as of 7:30 p.m. Wednesday, but it led the Army to lock down the post, located south of Louisville and north of Elizabethtown, according to early news reports by Fox News and other outlets.

The shooting took place near the post's 3,800-employee Human Resources Command at the post, Fort Knox Public Affairs Officer Kyle Hodges told WAVE 3 TV.

The lockdown was lifted shortly after 7 p.m., a Fort Knox spokesman told WDRB News, while authorities investigated the shooting incident -- though the post is in a state of heightened security and traffic to and from the base is reportedly closed.

There has been no information released so far regarding the specifics of the shooting, including if there were any deaths or injuries and whether or not law enforcement have arrested or identified a suspect or suspects.

Fort Knox is world-famous because of its proximity to the nearby U.S. Bullion Depository, which holds 147.3 million ounces of the nation's gold reserves and has at times held the U.S.'s Declaration of Independence, Constitution and Articles of Confederation, Lincoln's Gettysburg address, three volumes of the Gutenberg Bible and Lincoln's second inaugural address.
